We currently have a family plan with Verizon and all got iPhone 6 phones on launch day for the subsidized price. We're thinking about switching to T-Mobile as we would be saving a little over $200 a month to do so. According to a Verizon chat representative, the only fees we would incur for canceling our Verizon plan would be the ETF fees, which T-Mobile is agreeing to cover. Is there something we are missing? Would there be any other fees? Is there a catch? I know we'll receive pre-paid cards from T-Mobile - can we use these to pay the Verizon ETF fees?
